FEEDlNG-UP MACHiNE FOR POLlSHiNG TOOLS.

SPECIFICATION forming part of Letters Patent No. 504,593, datedSeptember 5, 1893.

Application filed April 10, 1893, Serial No 1 (N0 model) To aZZ whom itmay concern:

Be it known that I, LonEN W. KIMBLE, of Toledo, county of Lucas, andState of Ohio, have invented certain new and useful Improvements inFeeding-Up Machines for Polishing Tools; and I do hereby declare thatthe following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the figures of reference marked thereon, which form part of thisspecification.

My invention relates to a feeding up machine for polishing tools, andhas for its object to provide automatic means for feeding the pumice orputty to the brush.

A further object is to provide a feeding up machine in which a brushshall be caused to travel in an elliptical circuit to cause the same todip into the liquid material with a progressive movement approximatelyin a horizontal line, and then rise in an approximately vertical line tocontact with the polishing brush or wheel to supply the material to thebrush or wheel, and afterward descend in an elliptical circuit in orderthat the pumice or other polishing material may be applied at regularintervals, and without splashing the liquid material by the movement ofthe brush.

A further object is to provide a compact and portable machine of thischaracter, With provision for convenient attachment to the brush frame,with an arrangement by which power may be transmitted from the brushshaft.

The invention consists in the parts and combination of parts hereinafterdescribed and pointed out in the claims.

In the drawings: Figure 1 is an elevation of a complete machine, shownas attached to a trough, one side of the latter being removed todisclose the mechanism. Fig. 2 is a plan view of the same. Fig. 3 is adetail view of the brush arm, shown partly in section.

My invention is especially adapted for use for glass polishing tools,where the pumice or putty is applied at intervals to the brush or wheel,and is designed to dispense with the manual application.

1 designates hangers in which is journaled a shaft 2, upon which issecured the polishing tool 3, which in the present instance I haveillustrated as a brush, there also being a pulleyet upon the shaft,which is connected with the line shafting by belt 5, by which thepolishing tool is revolved.

While I have shown and described the aforesaid construction of polishingframe, I wish it understood that I may employ any form of frame andmechanism for revolving the polishing tool, as the feeding up mechanismmay be attached to any construction of polishing machine.

6 designates a frame, which is shown in the present instance as anelongated box, on which is secured a shaft 7, in boxes 8 attached toeach side of the frame, said shaft being stationary, and is secured frommovement by means of screws 9 bearing upon the same. Loosely securedupon the shaft is one end of an arm 10. A belt 11 passes around theshaft 2 and transmits motion toa pulley13 mounted upon one end of ashaft 12, and upon the opposite end of said shaft 12 is a pulley 16around which passes a belt 18 and drives a pulley 17, mounted upon ashaft 14: journaled in the hanger screwed to the side of the frame 6.Shaft 12 is j ournaled in a bearing on an arm 19 pivotally secured atone end to a lever 20, which is in turn pivoted to an extension 21 ofhanger 15, the outer end or arm 19 being weighted by means of weights22, said arm serving as a belt tightener to tighten belts 11 and 18respectively.

23 designates a crank arm secured upon shaft 1%. To the outer end ofsaid arm is a pin 24, upon which is pivotally secured one end of a guidelever 25, the opposite end of the lever being pivotally secured on a pin26 upon arm 10.

27 designates the brush arm pivoted at one end to arm 10 at 28, abovethe lever 25, the brush 29 being secured at the opposite end in thebrush holder 30, which is adjustably secured upon the brush lever 27,and comprises a plate 31 upon which the brush is laid, and is clamped bymeans of the clamp arm 32, journaled on pin 83. Substantially midway ofthe brush arm and formed in the same is a slot 3e through which the pin24: passes, said slot having an inclination substantially sixty degreesfrom the body of the brush arm, and

extends below the same, the slot running substantially parallel with thesame.

35 designates a trough for holding the liquid material to be fed to thepolishing tool, said trough being below the brush arm, and in a verticalline therewith.

In operation, the polishing tool being revolved, revolves shaft let andcrank arm 23 which forces arm 10 back, and also pulls upon the brush armto cause the pin 24 to travel down in slot 34: in the direction of theslot, thereby lowering the brush in a line with the slot, (see dottedlines Fig. 1.) As crank arm 23 continues to move, the slot is in ahorizontal position and the pin 24 traveling therein will give thebrusha substantiallyhorizontal movement in the liquid material in thetrough. A further turn of the crank will cause the arm 10, guide lever25, and brush lever 27 to be in a horizontal line, when the crank 23will raise the brush in an are substantially vertical to contact withthe brush, and upon the remainder of the turn of the crank arm, thebrush is given aturn to perform a downward movement as has beendescribed. By means of the elliptical circuit traversed by the brush,the brush not only has a progressive movement in the liquid material,but has an easy movement and avoids throwing or splashing of thematerial.

It will be seen that by securing the brush arm adjustably, the brush maybe set for different sizes of polishing wheels, also by means of thepivoted belt tightener the feeding up mechanism can be attached to anyheight of polishing frame.

What I claim is 1. In a feeding up mechanism for polishing tools, atoolshaft and tool, a brush lever having a slot intermediate its ends, arevoluble shaft having a crank arm, and a pin secured upon said arm andengaging the slot in the brush lever, whereby the brush is given anelliptical motion.

2. In a feeding up mechanism, a tool shaft and tool, a revoluble shaftcarrying a pulley and crank arm, a weighted arm carrying a shaftprovided with pulleys at each end,belts connecting the tool shaft andcrank shaft, a brush lever having a slot, and a pin mounted upon thecrank arm and engaging the slot in the brush lever.

3. In a feeding up mechanism for polishing tools, a tool shaft, a shaftactuated thereby, a crank upon the last'named shaft, a brush leverpivoted at one end to a pivoted arm and carrying a brush at the oppositeend, a slot in the lever through which a pin of the crank passes, andaguide lever connecting the pin and pivoted arm.

4. In a feeding up mechanism, a tool shaft and tool, a revoluble shaftcarrying a crank arm provided with a pin, a stationary shaft having anarm loosely mounted thereon, a brush lever pivoted to the end of saidarm, and slotted intermediate its ends, and a guide lever connecting thecrank and pivotal arms.

5. In a feeding up machine for polishing tools a tool shaft, a brushlever actuated thereby, said lever having a brush holder adj ustablysecured thereon, a pin in the brush holder, and a cam lever secured uponthe pin for clamping the brush.

In testimony that I claim the foregoing as my own I hereby affix mysignature in presence of two witnesses.

LOREN IV. KIMBLE.
